Letters Patent No. 93,951, dated August 24,1869.

The Schedule referred to in these Letters Patent and making part of thesame.

To all persons to whom these presents may come: k

Be it known that I, HENRY M. BEECHER, of I Plantsville, of thevcounty ofHartford, and State of Connecticut, have 'made a new and usefulinvention,

having reference to Dies for the Formation of Car-` riage-ShaftConnections or Shackles; and do hereby declare the same to be fullydescribed in the following 1 specificatiom and represented in theaccompanying drawings, of whieh- Figure l is a front-end view,

Figure 2, a bottom view, and

Figure 3, a top view of a shaftfshackle blank, as it is swaged outpreparatory to having its arms bent up, with respect to the shank, inmanner and by mechanism as hereinbefore'desclibed.

Figure 4 is a top view,

Figure 5, a side'elevation, and

Figure 6, a frontend view of the shaft-shackle blank, as bent and formedby the said mechanism.

Figure 7 is a top view,

Figure 8, a transverse section, and

Figure 9, a longitudinal section of the lower or stationary die,employed in effecting the bending `and formingof the blank. Y

lFigure l0 is an under-side View,

Figure l1, a side View, and

Figure l2, an end View Of the dropdie. y The object of the stationaryand drop-dies to be hereinafter desclibed, is to impart to the article,or shackle-blank, as exhibited by figs. l1, 2, and 3, the form of thatshown in figs. 4,' 5, and 6. In these latter figures it will be observedthat the arms a a of the cross, shown in figs. 1, 2, and 3, have beenbent up into, or, about into. parallelism with each other, and so as tostand at right angles, or thereabout, to therhottom of the shank b, thevertices of the angles of the shank, and arms being completed.

It will be seen` that the arms are pressed' down, so as to project atequal distances from the shank.

The blank, shown in figs. 1, 2, and 3, is rst swaged with projections oc, which, when the arms are bentA as described, serve tofilloutandcomplete theup blank at and near the vertices of the armsandshank.

The plate of thelower or stationary die is shown at A, as' provided witha semi-cylindrical recess or die, d, which,with another such recess ordie fl, formed in the drop-die B, serves to complete the round part orhead e ofthe cross.

angles of the This plate A may be in one piece with the bedblock C, orit may be separate therefrom, and be slid into a groove or channel, f,made through it.

VAnn-dies!! g are arranged on opposite sides of the channel f,and extendup from the plate A, in manner as represented.

They co-Operatewith the palt '71 and two semicircular archesor'upsetting-ydies, i fi, formed in the drop-die B, in manner asrepresented. v Leading upward from the arm-dies, and (formed inmanner-as .shown) in posts k k, erected On the bedblock, are tworecesses or bending-guides l Z, curved and otherwise formed, as shown inthe drawings.

There is, a -hollow or die n, in the bottom of the drop-die, such beingto operate with the flat surface 11, of the plate A, in giving form tothe shank b of the shaft-shackle, as shown in gs. 4, 5, and 6.

In using the dies, the blank is to be so laid on. the lower one, withthe arms resting in the bending-guides, after which the drop-die is tobe forced down upon the blank, so as to crowld it downinto-thebed-block, and the aim and head-dies thereof, so as to-cause thearms to bend up into right angles with the. shank and enter theupsetting-dies, and be crowded'down to a level with each otberby them.

I claim as my invention, in the above-described mechanism, thefollowing, Viz:

The combination and arrangement of the bendingguides l l, and thearm-dies g g, with the' bed-plate A and the drop-die B.

Also, the combination and arrangement of the upsetting-dies i. i, withthe drop-die B, and with the arm-dies g g, bending-guides l Z, anddie-plate A of the bed-block.

Also, the combination of the head-dies d il', with the die-plate A, theldrop-die B, the arm-dies g g, the bending-guides l l, and theupsetting-dies t i.

Also, the combination and arrangement of the' shankfdies n p, thehead-dies d d', thel arm-dies g g, the upsetting-dies 'l t, and thebending-guides Z l, the whole being applied'to the bed-block and thedropdie substantially in manner and so as to operate as and for thepurpose Or purposes hercinbefore specified.

HENRY M. BEECHER.
